Timers allow you to automate your device based on time triggers

To control a device locally 16 timers are programmable. They can be configured with the Timer<x> command followed by a JSON payload with optional parameters. For example:

Timer 1 will ENABLE output of POWER1 at exactly 2:23 every Tue/Wed and Sat

Timer1 {"Enable":1,"Time":"02:23","Window":0,"Days":"--TW--S","Repeat":1,"Output":1,"Action":1}

Timer 4 will TOGGLE output of POWER2 within a 30 minute window centered around 16:23 each Sunday, Monday, Thursday and Friday and will disable (disarm) after executing.

Timer4 {"Enable":1,"Time":"16:23","Window":15,"Days":"SM00TF0","Repeat":0,"Output":2,"Action":2}

When Mode 1 or Mode 2 is used, Latitude and Longitude are required. In that case the Time value is always used as an offset from sunrise or sunset, so make sure to set it to 00:00 if no offset is wanted. Timer 1 will ENABLE output of POWER1 2 hours and 23 minutes before sunset every day of the week.

Timer1 {"Enable":1,"Mode":2,"Time":"-2:23","Window":0,"Days":"11TW11S","Repeat":1,"Output":1,"Action":1}

introduced in version
Timers Timers control
0 = disable all timers  » v6.2.0

JSON Payload Anatomy~

JSON Name JSON Value
Enable 0 = disarm or disable timer
1 = arm or enable timer
Mode 0 = use clock time
1 = Use local sunrise time using Longitude, Latitude and Time offset
2 = use local sunset time using Longitude, Latitude and Time offset
Time When Mode 0 is active
> hh:mm = set time in hours 0 .. 23 and minutes 0 .. 59
When Mode 1 or Mode 2 is active
> +hh:mm or -hh:mm = set offset in hours 0 .. 11 and minutes 0 .. 59 from the time defined by sunrise/sunset.
Window 0..15 = add or subtract a random number of minutes to Time
Days SMTWTFS = set day of weeks mask where 0 or - = OFF and any different character = ON
Repeat 0 = allow timer only once
1 = repeat timer execution
Output 1..16 = select an output to be used if no rule is enabled
Action 0 = turn output OFF
1 = turn output ON
2 = TOGGLE output
If the Tasmota Rules feature has been activated by compiling the code (activated by default in all pre-compiled Tasmota binaries), a rule with Clock#Timer=<timer> will be triggered if written and turned on by the user.
If Rules are not compiled, BLINK output using BlinkCount parameters.


In order to set a timer to use the automatically calculated sunrise or sunset time, the latitude and longitude of the location as decimal degrees needs to be entered using the respective commands.

By default, Tasmota calculates the times of the actual sunrise and sunset. Starting with version, it is possible instead to use the beginning and ending times of civil, nautical or astronomical twilight. In particular, civil twilight is the period of time when the sun is below the horizon, but artificial lighting is not yet needed.
